Title: Wind-screening blind for roofed balconies
Inventor: KRUELLKE ERICH
IPC: E06B9/386
Filed: 1988-07-21
Abstract: The wind loading on balconies, predominantly in the case of high-rise buildings, is so great that, even in the event of pleasant weather, use of the balconies is often not possible. The wind-screening blind is intended to remedy this. In contrast to other blinds, the wind-screening blind is not let down, but is drawn upwards from the bottom until screening against the wind is ensured. By fully drawing up the blind, the hothouse effect is produced. The blind comprises transparent plastic lamellae which are stamped in the form of an S. The S-form effects the stability of the lamella, prevents rattling and ensures that the blind is collapsed in a satisfactory manner when it is let down into a collecting casing. The lamellae are held together by bands of material which are adhesively bonded on the lamellae on one side. Worked into the bands of material, at specific spacings, are annular eyelets which slide on vertically braced cables and thus permit the blind to be raised up and let down. The application of this invention is suited mainly for balconies, but also for terraces, forecourt restaurants and greenhouses.

Title: Method for recovering binary information from an errored baseband signal and an arrangement
Inventor: DRINDA KLAUS-JUERGEN DIPL ING
IPC: H04N7/035
Filed: 1988-11-15
Abstract: To recover binary information from an errored composite baseband signal, in particular a D2-MAC signal, a control signal for a control amplifier (V) is derived from a peak value detection (SD1, SD2). Signal components which lie outside this data burst are blanked out in the control procedure. The output signal of the control amplifier (V) is fed to a duobinary-binary decoder (DB) whose discriminator thresholds are controlled according to the positive and negative peak values of the data burst. Due to the measures of the invention, the duobinary-binary decoder (DB) always operates in optimum fashion independently of the signal amplitude of the signal to be decoded. <IMAGE>

Title: Method for controlling the exhaust gas composition
Inventor: SCHULTE ERASMUS DR
IPC: F02D41/00
Filed: 1988-11-24
Abstract: Mixture-forming systems in multi cylinder internal combustion engines are known, in which only one lambda probe is arranged in the flow of hot exhaust gas. This provides only the mean value for the exhaust gas flows of all cylinders. With the method according to the invention it is possible to adhere strictly to  lambda  = 1 at each operating point, the following steps being provided for this purpose: the lambda probe signal is divided up into time segments which are assigned to each cylinder as a function of the firing order and the assigned lambda probe signal is then processed into a correction signal which is applied to a throttle element adjuster or to the fuel injection valve or valves according to the intake order of the cylinders. The efficiency of the catalytic exhaust emission control can thereby be increased and the internal combustion engine operated in a road vehicle.

Title: Use of oil-free compressors and spray guns with pivotable nozzles in order to spray items to be baked and baking moulds with liquid edible substances
Inventor: FRISCH GERHARD
IPC: A21C9/04
Filed: 1988-11-26
Abstract: Liquid edible substances and separating agents have hitherto been applied to items to be baked and baking moulds by means of brushes or other implements of a solid type. Such operations are very time-consuming, are not pleasant, are imprecise and therefore use far too much of the substance to be processed. Furthermore there exist items to be baked which cannot be treated in this manner or can only be treated to an unsatisfactory extent. Spraying the substances in question (such as apricot syrup, beaten egg and separating agent) by means of an oil-free compressor and a spray gun having a pivotable nozzle saves time and material, is pleasanter, makes it possible to protect the items to be baked more effectively, improves the appearance and can be used to treat all items to be baked in future. The use of oil-free compressors and spray guns with pivotable nozzles in bakeries and operations of the same generic type.

Title: Dry-drilling extraction system
IPC: E21B21/16
Filed: 1989-03-18
Abstract: Dry-drilling extraction systems are designed to save energy and space by the bunker being arranged upstream of the filter and forming a construction unit with the filter. Both the bunker and the filter are accommodated in a common housing in such a way as to be separated from one another by a baffle system. In this arrangement, by appropriate discharges and a shared pre-mixing conveyor, the appropriately separated coarser material and the fine-grained material separated in the filter are then mixed with one another and bonded by water in such a way that a pasty and easy-to-convey mass results which can then be removed via the conventional chain or belt conveyors. The housing accommodating the bunker and filter is constructed on the chain conveyor and thus in addition takes up little space and can follow the roadway drivage without problem. Energy can be saved by the integration of bunker and filter and by the other skilful allocation of the individual transport systems, in which case the requisite radial fan can be attached directly to the filter. <IMAGE>
